These video clips show how the stunts in Concrete Circus were set up and rehearsed. All the stunts feature in the show itself. The stunts are carried out by experts in a controlled environment.
There are safeguards in place for the stunts (for example, for the fire stunts, the paste going on to Blue's legs is the flammable material, and he's wearing a cooling protective layer beneath his jeans).
The film-maker had permission to film in all locations you see in the clips. Thorough risk assessments were carried out and all stunts were performed under the supervision and instruction of a stunt co-ordinator.
Don't try these stunts yourself.
We suggest they're viewed by over 18s only.
